Jalapeño poppers, or jalapeño bites, are jalapeñopeppers that have been hollowed out, stuffed with a mixture of cheese, spices, and sometimes ground meat, breaded and deep fried. Sometimes called an armadillo egg, especially if wrapped in bacon or sausage meat to give the appearance of an armadillo shell[1][2], a term in use since at least 1972 in Texas, antedating the trademark on "Jalapeño Poppers".[3] As chile relleno can be made with jalapeño, the jalapeño popper is probably a Tex-Mex version of that dish.[4] The name Armadillo Eggs likely comes from the perceived similarity to Scotch Eggs.[3]

Primarily when smoked or grilled and stuffed with sausage they are also sometimes known as A.B.T or Atomic Buffalo Turds.[3][5][6]
